#139, "Recommended safe boost on stock internals on HRC stage 1 and FMIC"
What would be safe for HRC stage 1 on stock internals? Also I want to upgrade to a stage 2 with a FMIC, probably apexi. But, HRC wants 1200 bucks. Can I buy a used apexi FMIC and just get piping? Or can someone recommed a better FMIC? Any info would be appreciated. Thanks!!

Without an intercooler, i would be leery of running more than 5 lbs. of boost on any motor, but i believe the HRC kit is designed for 7 lbs. on stock trim?? Am i right? i got the star kit, so i am not sure. But anyway, like i said in the post before...it is not your internals that you need to worry about, it is how much fuel you are getting. You could have The strongest bottom end available, such as what Wyatt and others have, but you still can not really run any more boost than before you built it. Even forged pistons can't stand up to the extreme amounts of pressure that detonation causes. The best way to know if you are detonating is to get an A/F meter, and an EGT gauge. If it looks like it is running lean at whatever boost you have, then back it off. Thats my best advice, and i am sure that others will agree..

Jason is right ! 5psi on a non intercooled system is a max!! w/o the intercooler the charged air is pretty damn hot. One thing that you might wanna consider is setting up some sort of "cold air" intake that goes into the bumper of the car, that should drop the temp by at least 80 deg. depending on outside temps.
As for the intercooler setup, Spearco is the shit when it comes to intercoolers, not that apex is not good. But for around $500 you can pick up a nice Spearco intercooler.

I've got an HRC kit with Apex FMIC. The previous owner of the kit got the piping custom done. It is a tight fit, but the IC will fit with all the piping. You have to hack up the inside of the bumper a good bit to cram it all in there. I also had to make a new drivers side bumper support. Did it all this summer. I've got a few pics on my page listed below.
